> Common Library Functions

[confd\_lib\_dp(3)](https://nso-docs.cisco.com/guides/resources/man/confd_lib_dp.3)

[confd\_lib\_maapi(3)](https://nso-docs.cisco.com/guides/resources/man/confd_lib_maapi.3)

There is also a C header file associated with each of these manual pages:

`#include <confd_lib.h>`

> Needed when functions in the [confd\_lib\_dp(3)](https://nso-docs.cisco.com/guides/resources/man/confd_lib_dp.3) manual page are used.

`#include <confd_events.h>`

> Needed when functions in the [confd\_lib\_events(3)](https://nso-docs.cisco.com/guides/resources/man/confd_lib_events.3) manual page are used.

`#include <confd_ha.h>`

`#include <confd_cdb.h>`

```
#include <confd_lib.h>
#include <confd_dp.h>
#include <confd_events.h>
#include <confd_ha.h>
```
